Definitions

  • the invention relates to a multi-way valve arrangement and one with this provided fluidic actuator.
  • the multi-way valve arrangement comprises one another Combinable modular valve units, which are controlled by pilot valves controllable and freely combinable with one another using patch panels are.
  • This provides a high degree of flexibility in the choice of control for actuating single-sided and double-sided actuators reached.
  • the combination of several valve units is simplified, if the marshalling plates and the valve units are the same Have connection interfaces. Even more flexible control options arise if the pilot valves through the patch panels can be freely combined with the valve units and the pilot control valves and the marshalling plates to do so via uniform Have connection interfaces.
  • valve units can be opened at rest and at rest closing valve units can be combined.
  • Valve units thanks to lubrication-free valves such as diaphragm valves formed, for example 2/2-way diaphragm valves.
  • the pilot valves can, depending on requirements, by known rocker valves, Clapper valves with media separation in pulse or mono version or can be realized by low-power valves with pot magnet drive, which for lubrication-free operation is suitable.
  • the invention also provides the use of an inventive Multi-way valve arrangement in a fluidic control device with a fluidic actuator for the selective connection of the fluid connections the servomotor with a source of pressurized fluid or with a free one Pressure sink before.
  • a particularly variable control is possible if the actuator double acting and with two each other opposing pairs of connections is formed, of which each selectively through the multi-way valve arrangement with the Pressurized fluid source or can be connected to the pressure sink.
  • a pair of connections is Actuator with a valve unit that closes at rest and an in Quiet-opening valve unit connected, both shared by one Pilot valve are controlled, and the other pair of connections Actuator is with a valve unit and a connected at rest opening valve unit, both of which are common from be controlled by another pilot valve.
  • the principle of the circuit is two, which are controlled together via a pilot valve, valve units closing at rest with each other opposite connections of the two connection pairs of the servomotor connected, and two others via a different pilot valve controlled, at rest valve units are with the others mutually opposite connections of the two connection pairs of the Actuator connected.
  • Fig. 1 an interconnection of several pilot solenoid valves 10 L , 10 R and valve units with an actuator according to a first, symmetrical circuit principle is shown.
  • the valve units are designed as lubrication-free 2/2-way valves 1 L , 1 R , 2 L , 2 R in membrane design, each with an input connection, an output connection and a connection which opens into a control chamber 3 of the valve.
  • the valves designated by reference number 1 operate in a design in which a valve seat is closed by a spring 5 in the rest position, so that there is no connection between the input port P and the output port.
  • valve seat When the control chamber 3 is acted upon by a pressure supplied via the connection opening therein, the valve seat is opened against the force of the spring 5, as a result of which a connection is established between the inlet and outlet connection of the valve.
  • the valves designated by reference number 2 operate in a design in which a valve seat is opened via a spring 5 in the rest position, so that there is a connection between the input connection and the output connection R. If pressure is supplied via the control chamber connection, the valve seat closes, whereby the connection between the inlet and outlet connection of the valve is disconnected.
  • the pilot valves 10 L , 10 R can be formed, for example, by lubrication-free 3/2-way small valves.
  • the actuator is a double-sided actuator 20.
  • the actuator 20 has a chamber which is divided into a left and a right half 24 L and 24 R by a movable actuator 22 designed as a piston as shown in FIG. 1. Both chamber halves 24 L and 24 R each have a pair of fluid connections 26a, 26b and 28a, 28b
  • a left pilot valve 10 L is connected both to a first and to a second left two-way valve 1 L or 2 L via their control chamber connections.
  • a right pilot valve 10 R is connected to both a first and a second right two-way valve 1 R or 2 R.
  • the first left and first right valves 1 L and 1 R are each connected via their input connection P to a pressure fluid source (not shown).
  • the output connection of the first left valve 1 L is connected via an input connection 26a of the servomotor 20 to the left chamber 24 L of the servomotor 20, whereas the output connection of the first right valve 1 R is connected via an input connection 28a of the servomotor 20 to the right chamber 24 R of the Actuator 20 is connected.
  • the second left and second right valves 2 L and 2 R are each connected to the atmosphere via the outlet connection R.
  • the input connection of the second left valve 2 L is connected via an output connection 26b of the servomotor 20 to the left chamber 24 L of the servomotor 20, whereas the input connection of the second right valve 2 R via an output connection 28b of the servomotor 20 to the right chamber 24 R of the Actuator 20 is connected.
  • valves 1 L , 2 L , 1 R , 2 R are controlled by the corresponding pilot valves 10 L and 10 R , which in turn are controlled by a control signal U L or U R. That is, when a control signal is applied to a pilot valve, the two-way valves connected to this pilot valve are actuated.
  • the two chamber halves 24 L and 24 R can be controlled separately using the two pilot valves 10 L and 10 R according to the symmetrical circuit principle according to FIG. 1. The possible operating states of this arrangement are explained below.
  • valve seats of the first left and first right valves 1 L and 1 R are closed, while the valve seats of the second left and second right valves 2 L and 2 R are open.
  • both chamber halves 24 L and 24 R of the servomotor 20 are only exposed to atmospheric pressure, since there is no connection to a source of pressurized fluid.
  • the actuator 22 is thus freely movable ("floating circuit").
  • both chamber halves 24 L and 24 R are pressurized via the first valves 1 L and 1 R , the two "ventilation outputs" 26b and 28b of the chamber halves 24 L and 24 R are closed by the second valves 2 L and 2 R , respectively. If the pressure fed in via the first two valves 1 L or 1 R is of the same size, then the actuator 22 is fixed in a blocking position in this case, since the piston area of the actuator 22 is of the same size on both chamber sides.
  • Fig. 2 shows another interconnection of pilot solenoid valves 10 L , 10 R and valve units 1 L , 2 L , 1 R , 2 R with the actuator according to a second circuit principle.
  • the multi-way valve arrangement is similar to the arrangement shown in FIG. 1, but the arrangement according to FIG. 2 is based on a "crossover" circuit principle. It differs from the arrangement of Fig. 1 in that all valve units designed as two-way valves 1 L , 2 L , 1 R , 2 R work in a design in which the valve seat is closed by a spring 5 in the rest position, whereby as in 1, the two first valves 1 L and 1 R are connected to a pressure fluid source and the two second valves 2 L and 2 R are connected to the atmosphere.
  • FIG. 1 shows that all valve units designed as two-way valves 1 L , 2 L , 1 R , 2 R work in a design in which the valve seat is closed by a spring 5 in the rest position, whereby as in 1, the two first valves 1 L and 1
  • the left pilot valve 10 L is connected to the first left and second right valve 1 L or 2 R
  • the right pilot valve 10 R is connected to the first right and second left valve 1 R or 2 L is connected.
  • the individual valves are actuated via the pilot valve connected to the respective valve by means of a control signal.
  • the actuator 22 can be fixed in its own pressure by shutting off both chamber halves 24 L and 24 R from the pressure fluid source and the atmosphere.
  • Table 2 The possible switching states for the arrangement according to FIG. 2 are summarized in Table 2 below.
  • U L U R 1 L 2 L 1 row 2 rows effect 0 0 P to R to P to R to Drive fixed in self-printing 0 1 P to R on P on R to Drive to the left 1 0 P on R to P to R on Drive to the right 1 1 P on R on P on R on Short circuit P to R
  • FIG. 3 the connection of the pilot valves 10 L , 10 R and the modular valve units 1 L , 1 R, 2 L , 2 R is shown schematically by marshalling plates 30.
  • the modular valve units 1 L , 2 L , 1 L , 1 R are combined with the pilot valves 10 L , 10 R to form a cuboid unit.
  • the pilot valves 10 L , 10 R are connected to the first valve units 1 L , 1 R via an intermediate switching plate 30a, as is the connection of the first valve units 1 L , 1 R to the second valve units 2 L , 2 R via a switching plate 30b .
  • the pressure feed from the pressurized fluid source and the venting take place via a lateral switching plate 30c, which extends over the entire unit.
  • the output variables A and B are made available via a lower patch panel 30d.
  • the patch panels 30 can be adapted to the respective application. All patch plates 30, all pilot valves 10 L , 10 R and all valve units 1 L , 2 L , 1 R , 2 R have uniform connection interfaces.
  • a fluidic actuator realized with the fluid connections of a servomotor selectively connected to a source of pressurized fluid or to a pressure sink can be.
  • a particular advantage of the arrangement is that that also actuated only one actuator motor can be used by using only corresponding parts of the arrangement become.
